我省浅山实行绿肥冬播,初步获得成功,经生产试种增产效果良好。1979年至1981年试种面积分别为10亩、15亩和25亩,且因种植年限短,实践经验和研究资料积累不多,冬播技术在许多方面还没有达到成熟的程度,加上浅山地形变化大,气候条件复杂,因此,试种增产效果不太稳定,其主要原因是保苗率偏低所致。为了探明保苗率不高的原因,寻求有效的解决途径,兹就这方面的试验研究结果,作一初步总结分析。
Shandong Province, the introduction of green manure winter sowing, the initial success, the trial production by the production of good results. From1979to1981, the planting areas were respectively 10 mu, 15 mu and 25 mu. Due to the short planting life, little practical experience and research data, winter sowing technology has not reached maturity in many aspects, Topographical changes, the climatic conditions are complex, therefore, try to increase yield is not stable, the main reason is the seedling rate is low. In order to find out the reasons for the low seedling rate and to find effective ways to solve it, a preliminary summary analysis of the results of this pilot study is hereby given.
